Entrainment Mapping

open access: yesCardiac Electrophysiology Clinics, 2017
Mapping during ventricular tachycardia (VT) aims to elucidate mechanism, describe myocardial propagation, and identify the origin and critical regions of VT that can be targeted for ablation, most commonly with radiofrequency ablation. Most VTs in structural heart disease are due to macro-reentry in and around scar. A combination of mapping techniques,

Human chronotypes from a theoretical perspective. [PDF]

open access: yesPLoS ONE, 2013
The endogenous circadian timing system has evolved to synchronize an organism to periodically recurring environmental conditions. Those external time cues are called Zeitgebers. When entrained by a Zeitgeber, the intrinsic oscillator adopts a fixed phase

The effect of substrate roughness on air entrainment in dip coating [PDF]

open access: yes, 2004
YesDynamic wetting failure was observed in the simple dip coating flow with a series of substrates, which had a rough side and a comparatively smoother side.

Competing Effects of Droplet Sedimentation and Wind Shear on Entrainment in Stratocumulus

open access: yesJournal of Advances in Modeling Earth Systems, 2019
The joint effect of droplet sedimentation and wind shear on cloud top entrainment in stratocumulus is investigated with direct numerical simulations. Although it is well understood that droplet sedimentation weakens entrainment while wind shear enhances ...

A Theoretical Study on Seasonality

open access: yesFrontiers in Neurology, 2015
Additionally to being endogenous, a circadian system must be able to communicate with the outside world and align its rhythmicity to the environment. As a result of such alignment, external Zeitgebers can entrain the circadian system.

Advances in the studies of cloud entrainment and mixing process

open access: yes暴雨灾害, 2021
The entrainment and mixing process characterizes the interaction between cloud and ambient air, which is one of the most uncertain processes in cloud physics and dynamics.

Quantitative Prediction of Air Entrainment Defects in Casting Filling Process [PDF]

open access: yesArchives of Foundry Engineering, 2023
Air entrainment defect is a common type of defect in the casting process, which will seriously affect the quality of the casting. Numerical simulation technology can predict the occurrence of casting defects according to the evolution law of liquid metal

Surface oxide film entrainment mechanisms in shape casting running systems [PDF]

open access: yes, 2009
During the transient phase of filling a casting running system, surface turbulence can cause the entrainment of oxide films into the bulk liquid. Research has shown that these are detrimental to the material’s integrity.

A large-eddy simulation exploration of the assumptions used in retrieving entrainment from a mixing diagram approach with ground-based remote sensors [PDF]

open access: yesAtmospheric Measurement Techniques
Entrainment is a crucial component of the atmospheric boundary layer (BL) moisture and heat budget. While usually thought of as only entrainment flux, entrainment within the mixed layer budget equation is really composed of two terms: the flux of a ...

Influences of an entrainment–mixing parameterization on numerical simulations of cumulus and stratocumulus clouds [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
Different entrainment–mixing processes can occur in clouds; however, a homogeneous mixing mechanism is often implicitly assumed in most commonly used microphysics schemes.
